John Kellerman - Sisters in heat

"Coming! Steveeee! I'm coming! Ohhhh!"

The storm at her cunt quickened into white hot pleasure. The first surge of pleasure brought a cry from deep in her throat. Aching thrills ran up and down her pussy. She pumped the consuming itch that had invaded her clitoris, pumped it hard against the thick base of her brother's prick. Her willowy body shuddered with ecstasy. She whimpered uncontrollably.

Something was happening to Stevie too! His hands on her ass pulled and dug at the white meat of her asscheeks. He held his cock deep and gave rapid little fucks that stretched something inside her cunt.

Her come was devastating! She choked on the words of passion she tried to breathe into her brother's ear. She bit at his earlobe and drooled. Once she bucked so hard under him that his cock slipped out of her pussy and she whined like a cat for him to fuck her more.

"Stevie… Ohhhh honey Steve! Love you, love you, love you…"

And she clasped her thin legs tightly around his middle and fucked for all she was worth.

But Steve was acting funny… he was trying to slow down now, he was trying to be still. Robin couldn't be still. Her body snaked and writhed under him. She rubbed small hands up and down the small of his back, urging him to get his cock deep again, wanting him to stretch and make her a woman.

"What's wrong… Oh Steve… Ohhhh!"

Her orgasm was ending, slipping away on tingling tendrils of ravaged nerves. She fought to have it back… there was just the hint of a sparkle there deep in her pussy that said she might have another one if she tried.

Two comes!

Robin had never even heard of such things, couldn't bother with such details now. She worked her ass up and down, begging Steve to please fuck her.

"Be still… damn it, Robin, be still!"

"Oh Stevie, I just can't!"

"I've got to… stop… I… Oh damn it, Robin!"

It happened so fast that she thought Steve had flipped out or something. He yanked his throbbing cock of her pussy and pushed himself up on hands and knees. His face was twisted in agony.

Robin tried to understand what was wrong but the shock of her empty cunt was so sudden that she was gasping for air herself. She could clearly see her brother's cock. It dangled an inch from her belly and it was glossy with her slick juices. The flared crown was a deep purple and bigger than she'd remembered. At the slit-like orifice hung a huge milky droplet. It grew suddenly in size and oozed down in a string, puddling in her navel.

"Steve! What's wrong…"

"Touch me, Robin! Goddamn it you've just got to… hurry Robin, hurry!"

And then the truth was flashing in on her. He'd been about to come and pulled his prick out of her cunt before it was too late, before she got knocked up. She didn't know how a boy worked, didn't know that for him to stop like that was awful. But she was understanding it all within a few seconds. The twisted features of Steve's face were all the facts she needed.

She plunged her small hands down, down between their stomachs. The slick heat of his cockshaft brought a shudder of excitement to her lips. Even though her climax was over, she felt the new surge of lust. That prick was so big in her palms!

She smoothed back the skin and felt her own flesh grow immediately slick with her own juices. Steve groaned and pumped his hips so that the steely prick fucked in and out of the circle she made with her fingers. She rubbed the bulging veins, caressed the spongy tip with a thumb and forefinger. Steve's mouth fell open. A glistening strand of drool leaked from the corner of his lips.

"Uhhhh… oh God, Robin do it faster, honey!"

She jacked the skin up and down. It moved tautly but easily on the hardness underneath and when she brought her hands toward the tip, the bursting thing grew even larger, darker. His cock was hot! Hot with trapped blood!

Another milky droplet formed at the tip, dangled for a moment and fell again to the slimy lake that was forming in her belly button. She was surprised at the heat of his seed. And the sharp odor was new to her, a little shocking. Her nostrils flared.

She flopped her head on the pillow and jacked the skin up and down while Steve's balls swung heavily against her hands.

"Touch my balls… like that! Hurry, Robin… Aaahhhnnn!"

Robin caressed the mushy wrinkles of his balls. She was surprised at the largeness of the twin eggs and wasn't sure exactly what Steve wanted her to do. Then she felt it. Above his balls, where the sac grew out of his body, she sensed a pulsing, a throbbing. She lifted his balls upwards, pushed a curious finger against the lump that was partially inside her brother's body. The lump, whatever it was, was bulging powerfully in a rhythm that matched the swell of his darkly ridged glans.

A much bigger glop of white seed bubbled out of the slit of Steve's cock and oozed back under the head where Robin smoothed it back along his shaft. Her jacking movements made sexy, sucky sounds and she saw that more thick cream was bubbling from Stevie's cock, slipping back where it was caught by her moving hand and worked along the length of his shaft. His cum clung in strings across her knuckles and there was more pumping out at every second.

"Ghaaaa!" Steve groaned.

A sharp jet of semen spat in an arc onto one of Robin's tits. Then another! It was coming hard! Robin whimpered excitedly at the slick heat, the excitement of something she'd never experienced.

"Am I hurting you, Stevie?"

"God… noooo! Don't stop!"

She palmed his balls, rubbing and wallowing them around in the hot sac. She couldn't feel anything special happening to them, but knew they were pumping potent sperm forcefully from the orifice of her brother's cock. Both her tits were glistening with warm strings of jizz. Some leaked down under her arm and, as she leaned forward to jack her brother off, it was spread in a slick, sticky coat over her skin.

Steve collapsed beside her after one final bolt of semen glopped thickly onto Robin's belly. She petted his shoulders, kissed his cheek. She daydreamed, her eyes closed so that she could make up what she needed. Her brother's warm body did the rest. She imagined them living on some island with, nothing to do but play and eat and fuck. The fact that this was incest didn't matter. The only thing that made it wrong was other people. On this island there was only the two of them.

When Steve rose suddenly from her arms and went into the bathroom, she didn't understand what was happening. He closed the door and she thought she heard him crying.

"Steve? Is something wrong?"

"You'd better get back home, Robin."

His voice sounded muffled and strange through the door. She looked at the mess on her tits, the drying cum, the red places where Steve, her brother, had kissed her. She dabbed herself off as best she could and got into her clothes.

"Steve, I have to see you before I go. Don't just run me out like this."

She was close to tears herself. Steve wouldn't answer, wouldn't open the door.

Robin went out the back door and down the alley. She was sore through the crotch. But she couldn't think of anything but the sin she and her brother had joined in. It had finally come to pass. Her brother had slid his hard cock up into her body. They had fucked like animals with no other thought but their pleasure.

Robin cried as she walked. What had been a paradise of love just moments before was now a shambles in her mind. Poor Steve, he had realized it before she had.

The bus came and Robin got on and went to the very back seat.

"What do ya want to see Nat for?" Gloria stood in the doorway with one hip cocked, a beer in her hand. There was loud music playing on the phonograph and Marcia could see a man's shoes beneath the doorway that led to the living room.
